YES YES YES !!
I towed for 5 years with a 2.5 miggy, it was so good I changed to a newer one, ok it is 3.2 with a small body-kit, but still a miggy. We actually went looking for an 03 but this one sort of said "buy me" ....
I have been towing for 20 years on a regular basis and have had 4 tow cars, Mk 2 Granada, Ford Scorpio, Miggy 2.5 and now the 3.2. I always swore the scorpio was the best towcar in the world until I got the miggy, and the only difference in the 2.5 and 3.2 is the greater power which at towing speeds makes little difference, you just get there slightly quicker.
Both miggy's have been Elite's, deliberately, as I wanted the self leveling suspension and the self leveling HID lights - and the other toys are nice anyway
As to reliability, in 5 years the 2.5 let me down once. We stopped in a hillside layby on the Loire Valley to take some piccies, when we restarted it seems the aircon fans and the rad fans all kicked in at the same time ... this blew the large fuses for the fans ... so the motor got pretty hot pretty fast, pulled over and after (eventually) fitting new fuses we were good to go. That car towed to France every year, including down to Bordeaux in August .. which was damned hot !!
I've only had this one since January but it handles exactly the same, and I'm pulling a 1600 kg caravan most weekends.
The ONLY downside to a miggy as a towcar is the fuel consumption, I've solved that by converting to LPG ..
I wouldn't hesitate to commend a miggy as a tow car, powerful, rear wheel drive, easy to drive
